I need some tips please guys.

I'm converting my PNV r30 coupe to manual as i've finally found everything I need.

How do i get the bits out of the manual r30? Do i have to get the dash out to get the pedal box out? Any suggestions on driveshaft and clutch etc?

just general not R30 specific

tailshaft is easy, 4 bolts on the diff, use 2 spanners. if its got a centre bearing unbolt that and slide it out of theback of the gearbox

drain the clutch lines via the bleed valve (or unbolt the line) on the clutch slave, unbolt it from the bellhousing

undo any earth wires, reverse swicth wires, ect going into the box. make sure you get all of them

unbolt the shifter linkage, youll probably have to take out the centre concole and the shifter boot. might also get away with not having to unbolt it.

start undoing the bellhousing bolts, using lots of extentions.

undo the gearbox Xmember bolts. this is where it gets dangerous as the box is only supported by the input shaft

everything unbolted and out of the way, slide the box back and once the shaft is free, drop it out. if its a smaller box you should be able to lift it yourself, but it sucks doing it on the ground!

umm clutch stuff unbolt the master from the firewall (careful of spilling fluid) and unbolt the linkage. then shove yourself doen under the dash and get the pedal out and stuff out

They're pretty damn heavy. We used two jacks and three people to be safe. It was easy enough, just keep the box stable as you lower it down. You might want to unbolt one of the front wheels so that you can get the box out easily once removed.

Sure you've got everything you need?

I got it out.

I got:

Gearbox

Pedal box

Clutch Cylinders

Front and rear driveshafts

This driveshaft cage

Gearbox crossmember

i jsut have to get a clutch and flywheel (sorting that out now).

DO you guys reckon it'll be possible to install the manual box with the car on axle stands?? I'll be doing it as soon as i get my clutch and flywheel.

Also, the plug that goes to the loom on the manual. I noticed my auto has the same plug. Will that be all plug & play??

We did the whole thing with axle stands. It was a pity fiddly getting the box fitting onto the spline but realised to get the teeth fitting it was easiest to have one person moving the shaft atthe back of the box at the same time as wiggling the box in. Sorry if that's a poor explanation.....

Got spigot bush?

I get what you mean about wiggling the box on and moving ths shaft at the same time to get it to line up etc?

Spigot bush...shit...

Where does the spigot bush go??

What about the FLYWHEEL, I don't see that on your list George.

what - turn the bushes upside down? hehe

That's the one Harry, but different to stagefumer, by turning the bushes 180 degrees in the shift lever, it actually shortens the throw inside the gearbox, whereas just shortening the length of the lever does nothing to the shift travel.

Does exactly the same thing in our R30's that $150 plus does to S13 & R31/32 etc.

Cheers, D

      [HOW-TO] Winter Steam-Clean & Odour Removal in 30 min

      Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 🤣, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up

      [HOW-TO] Winter Steam-Clean & Odour Removal in 30 min

      Yeah, I'm not interested in wetting the carpets, and I don't care about brown dirt/dust that lives deep in the pile or underneath. It's not like I crawl around on them in my birthday suit or eat dropped food off them (because there is never any open food in my car). The seats are alcantara (cheap Chinese imitation alcantara, to be sure!) with barely 1" of foam pad behind the surface. That's not getting wet either. Any car that I would be happy to get the interior wet, I would not care to put the effort into.

      [HOW-TO] Winter Steam-Clean & Odour Removal in 30 min

      We have one that holds 2.8L of water. On floor carpet that hasn't been touched in 2 or 3 years, will take a minimum of 2 fills of the tank to do a bedroom, and that's going AROUND the bed.   In the cruiser, I used an ENTIRE 2.8L tank, just on the front passenger footwell. But it had some fungus growing, and had been full of mud from being used as a 4WD for many years. I can do that floor again, and it will still pull mud out. However, the water now only looks dirty, not pitch black and leaving full sludge in the bottom of the tank it sucks back into. Oh, and, this is about a $1500 unit.
